▎ 摘 要
NOVELTY - Oxide substrate-assisted preparation of large-size monocrystalline graphene comprises placing metal foil on oxide substrate, and growing high-quality large-size monocrystalline graphene on metal foil surface. USE - Method for oxide substrate-assisted preparation of large-size monocrystalline graphene (claimed). ADVANTAGE - The method is simple and fast, has short growth period, and produces high-quality large-size monocrystalline graphene.
